What Are the Main Reasons for the Failure of the Plate Heat Exchanger?
What combined load may make the fixed tube sheet heat exchanger fail to meet the strength conditions, and use other forms of heat exchangers (such as U-shaped tube type)?
Under the combined action of the very high tube pass pressure and the differential temperature load of the large tube shell pass, the fixed tube sheet heat exchanger can not meet the strength requirements.
Because to reduce the large temperature difference stress, it is necessary to set an expansion joint, but this will cause the tube and the tube sheet to generate great stress under the action of a high tube pass pressure, making it unable to meet the strength conditions, so other heat exchange types are selected.
What are the main reasons for the failure of the plate heat exchanger?
1. Seal failure
2. Equipment blockage
3. Equipment scaling
4. Corrosion
